SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 555,368, dated February25, 1896.

Application filed August 23, 1895.

T all whom it may concern.-

Be it known that we, GEORGE IV. GARDNER and LEwIs APPLETON, ofPhiladelphia, in the county of Philadelphia and State of Pennsylvania,have invented a new and Improved lYindow-Fastener, of which thefollowing is a full, clear, and exact description.

' Our invention relates to devices for fastening windows and likeobjects, and the object of the invention is to provide afastening deviceadapted for application to a window without materially marring the same,and which may be expeditiously and conveniently manipulated to permitthe window-sash to be raised and lowered, or to lock the windowsash indesired position.

Another object of the invention is to provide a window-fastener whichwill be exceedinglysimple, durable, and economic in its construction,and which may be manipulated with but one hand.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the device applied to a window. Fig. 2is a verticalsection through the said device. Fig. 3 is a bottom planview of the bolt, and Fig. i is a section taken substantially on theline at i of Fig.

In applying the invention to a win (low-frame A, a bead of thewindow-frame is provided with a rack A, and the teeth of this rack arepreferably made flat on the top and have a downward inclination attheirinner faces, as is best shown in Figs. 1 and 2.

The device proper comprises a casing B, a bolt 10 having slidingmovement within the said casing preferably between guides 11 and 12, anda shaft 13 adapted to actuate the said bolt, and the said shaft is heldto turn between the bottom portion of the bolt 10 and a lower guide 14.The bolt 10 passes outward through one end of the casing B and isinclined at its outer extremity in order that it may fit snugly to theinclined surface of any one of the teeth and rest upon the flat sur-Serial No. 560,230. (No model.)

face of the tooth below which its inclined face engages. The casing B issecured by bolts, screws, or otherwise to the window-sash 0,

preferably at the bottom rail thereof, as is also illustrated in Fig. 1,and as shown in Fig. 3 the said bolt upon its under face near its innerend has a diagonal rib 15 formed thereon, and the said rib is adapted toenter a diagonal or inclined annular groove 16 made in the inner end ofthe shaftl3. The shaft 13 extends out through the casing at the sideopposite that through which the bolt 10 is carried, and the said shaftat its outer end is journ aled in lugs 17 spaced a suitable distanceapart and formed upon a plate 18, the latter being adapted to be securedto the outerface of the window-sash, preferably at or near the centralportion of its lower end. A handle 19 is made upon the outer face of theaforesaid plate, ordinarily beneath the apertured lugs 17 in which theshaft 13 is journaled, and between these lugs a thumbplate is secured onthe shaft 13, and a spring 21 attached to the plate 18 extends upward toan engagement with the body portion of the said thumb-plate, as shownbest in Fig. 4.

In the operation of the device, when the window is to be lowered thehandle 19 is grasped by the fingers of one hand and the thumb-plate 20is pressed downward against the tension of the spring 21 with the thumbof the same hand, and in so manipulating the thumb-plate 20 the shaft 13will be rotated sufficiently to cause the bolt 10 connected with it totravel inward and clear the rack A. \Vhen the sash has reached itsproper position, upon releasing the thumb piece or plate 20 frompressure the spring will carry it to its original position and restorethe bolt 10 to a locking engagement with the rack. The same manipulationof the bolt 10 is required when the window is to be raised.

This invention is exceedingly simple, durable, and economic, and asheretofore stated may be expeditiously and conveniently applied to anywindow-sash and its frame.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent The combination, with a bolt, a shaftarranged'to actuate the said bolt when said shaft is rotated, aface-plate, a bearing on the on the thumb-plate in an upwardlydirection, face-plate for one end of the shaft, a thumbas and for thepurpose specified.
